NEW YORK (AP) – Billy Joel has acknowledged in a candid Howard Stern interview he tried heroin and said he almost formed a supergroup with Sting.

The piano man opened up Monday in a two-hour interview in front of 150 people in a New York City town hall setting.

The 64-year-old says he tried heroin once but it “scared” him. He says it was the inspiration behind the song “Scandinavian Skies” from his 1982 album “The Nylon Curtain.” He also says he talked about forming a group with Sting, Don Henley and “another guitarist.” He says someday they “might put together a silly supergroup.”

Joel watched Tony Bennett and Melissa Etheridge perform his hits in the town hall. Pink, Boyz II Men and Idina Menzel (ih-DEE’-nah mehn-ZEHL’) also performed during the three-hour event, which aired live on Stern’s SiriusXM radio show.
